Love it. One person's issue and everyone should stay away. Another suggests Campy - they got it right- except the poor schmuck who had a 1st gen EPS and brought it into my LBS - LBS couldn't get it working correctly - on the phone with Campy they told him, "Yeah, we fixed that in the next generation so your customer is out of luck."
Let's see, maybe we can find someone who had issues with shimano and then we'll have to go and find issues w/ traditional cable shift systems.
